1,229,749 I Specification of Letters Patent. Patented June 12, 1917. Application filed September 17, 1914 Serial No. 862,138.

To all whom it may concern:

Be it known that I, NEWMAN H. HOL- LAND, a subject of the King of Great Britain,

from the phonograph record may be transmitted to any desired distance." The principal object of my invention is to provide an improved device of the class described in which the'sound reproducing means is rendered inoperative when the sound recording meansis in position for operation, and vice versa, so that the possibility of interference of one of these means'with the operation of the other is'efiectively eliminated and an increased efliciency of operation" is obtained. Other objects of my invention will appear more fully in the following specification and appended claims.

In order that my invention may be more clearly understood, attention is hereby directed to the accompanying drawing forming a part of this specification and .in which' Figure '1 is a view partly in elevation, partly in section, and partly diagrammatic illustrating the inventiontand I Fig. 2 is a similar view of a modification. In both ,of the figures. like parts are designatediby the same reference numerals. Referring to the drawing, the numeral 1 designates a traveling carrier arm to which the sound box body 2 is pivoted, as by a pivot screw 3 and 'a' 'corresponding screw placed" diametrically opposite the same. The sound box body 2 has a downwardly and rearwardly extending arm4 to which arms 5 'onopposite sides of the arm 4 are pivotally connected, as at 6, 'for up and down movement A vibratory dia-' hragm 7 is mounted in a casing 8 which is carried by the arms 5, the interior of the casing 8 communicating with the inpreferred embodiment of my 7 terior'of the sound boxbody 2 by means of a hollowtubular connection 9. The speclfic construction thus far described is shown and described in detail in my co-pending application, Serial No. 831,695 filed April 14, 1914 and entitled Phonographs and is per ae no part ofthe present invention. A recording stylus 10 and areproducing stylus 11 are secured in any suitable manner to diaphragm 7, thereproducing stylus 11 .be-

ing shown in engagement with the record surface 12 and the recording stylus '10 out of engagement with said surface. tofacilitate the tilting of the sound box body 2 and the parts carriedythereby about the axis of the pivots 3 so as to bring either stylus at will into engagement with the surface 12, I prefer to provide the carriage 1 In order with a sleeve-like guide'13 in which an opcrating member 14 is arranged to recipro cate longitudinally. L The member 14 is provided with a slot 15 inclined to the direction of movement of the said member, this slot containing a pin 16 secured to a projection 17 extending upwardly from the sound box body 2. When the member 14 is moved from the position shown in Fig 1 toward the left, the pin 16' will ride upwardly in the slot 15, thereby causing the sound box to be tilted about the axis of the pivots 3 to move the stylus '11 out of engagement with the surface 12 and the stylus 10 into engagement with said surface. When the member '14 is again moved toward the right tothe position shown in Fig. 1, the sound box will be'tilted to move the stylus 10 out of engagement with the surface 12 and the stylus 11 into engagement with the said surface. j I

Communicating with the interior of the sound box body member 2 and extending upwardly' from the same is a hollow tubular neck'18 having hollow tubular branches 19 and 20 extending'laterally at an angle from the same. The branch 19- has mounted in the upper end thereof a telephone receiver 20" having the usual'diaphragm 21 adapted to be set into vibration by the electromagnets 22 in the telephone circuit to be hereinafter described. The" telephone receiver- 20" has a passage22 opening into the in: terior of the branch 19 so that the vibrations of the diaphragm 21 may be communicated receiver 37 from which it flowsthrough thev conductor 38, the switchv member 28, which isset into operation to reproduce the record,

electrical connectlon or engagement with the the parts '9 and 8; has

mounted in the upper -'end thereeif a telephone transmitter of suitabledesign. This transmitter may be constructed in the manner set forth in my copendingapplication" Serial No. 767,261, filed May 13,1913, and entitled Telephone transmitter. Thesaid transmitter has an outwardly flaring passage 24 communicating. with the interior of branch 20 so that the vibrations-of the dia phragm 7 may be communicated to the diaphragm 25 by the air in the casing the art 9, the sound. box-'2, the neck 18, the.

ranch 20,- and the passage 24.

The current for my-improved apparatus may be supplied by any suitablersource, such, for example, as a battery 26, one. terminal of which is connected as by a -condu'ctor 27,

to a switch member 28 which is secured to the sound box body 2. The other terminal of the battery may be connected to a conductor 29 which is electrically connected at the point 30 to a conductor 31, which connects the binding posts 32 and 33 on the receiver"20" and the transmitter 23 respectively. The other binding post 34 on' the transmitter 23 is electrically connected, as

rent flows from the battery 26 through the conductors 29' and 31 to the transmitter 23 and thence through the conductor 35 to the is now electrically connected to theconductor 38, and the conductor27 back to the battery 26. Accordingly, when the phonograph the vibrations imparted to the diaphragm 7 through the stylus 11 cause the transmitter,diaphragm 25 to be set into corresponding vibration and. to transmit its vibrations 'to the receiver 37- which may be at any suit-' able distance from the (phonographic apparatus. When the 'soun box body mem er 2 is tilted by the member 14 to bring the re cording stylus. 10 into engagement with' the record surface 12 and to remove the reproducing. stylus 11 from engagement with the record surface, the switch member 28 is moved out of electrical connection r enment with the "conductor 38 an into conductor 42. The current from the battery 26 now flows through the conductors 29 and 31 to the receiver 20", thence through the conductor 40 to the transmitter 41 and thence through the conductor 42, the switch member 28 and the conductor 27 back to the battery 26. -'The transmitter 41 may be located atv any suitable distance from the phonographic apparatus. With this arrangement of parts, undulations corresponding to the sound waves impressed upon the transmitter 41 will be conveyedto the receiver 20" and thence through the air in the parts 19, 18, 2, 9-and 8 to the diaphragm 7, the

vibrations of which will be recorded upon the surface 12 by the stylus 10. It is to be noted that the switch member 28 is electrically connected to only one of the conductoi's .38 and 42' at any given time so that when the recording stylus 10 is in operative position, not only is the reproducing stylus out of operative position but the current from the battery 26 is cut off from the transmitter 23 and the receiver 37. 'Likewise, when-the reproducing stylus is in engagement with the record, the recording stylus'is out of eIi+v ement with the record and the current rom the battery is shut off from the transmitter 41 and the receiver- 20", For this reason, interference of the recording instruments with the reproducing instruments or vice versa is effectively prevented andthere is a material saving of current from the battery 26.

In the modification shown in 2 an amplifying sound conveyer or horn 43 takes the place of the transmitter 23, the receiver 37 and the circuit connections between the same shown in Fig.- 1, and the receiver 20 is mounted directly in the upper end of the hollow tubular neck or passage 18 extending upwardly from the sound box body 2. The opening 44 between the horn 43 and the neck 18 is arranged tobe closed by a spherical valve member 45 when the recorder is in operative position soas to shut the horn 43 ofi' from the PaSage 18. 2, the-reproducin stylus isin operative osition and the va ve member 45 has -ro1 ed downwardly along the horn 43 away from the opening 44 and into engagement with the limiting pin 46 which extends across the said horn. When the member 14 is oper- As shown in Fig. 7

to pass through the opening 44. One of the terminals of the battery 26' is connected to' one of the binding posts 32'. of the receiver. 20 by a conductor, 29'. The other terminal of the battery is connected, by the con ductor 40'. to the transmitter 41 which letter is likewise connected to" the conductor 42" which extends adjacent to the under side of the switch member 28'. iswitcli member 28, is connected by the conductor 27 to the bindingpost 39 of the're'ceiver 20. With the parts in the positionshown,

in Fig. 2, the re roducing stylus is in en-" gagement with t e record surface and the free passage of the reproduced sound waves.

through the opening 44 and the horn 43 s ermitted, the recordin apparatus being moperative by reason 0' the fact that the switch member 2 is disconnected from the conductor 42' and the recording stylus is out of engagement with the record surface.

When the member 14 is moved to the left, the recordin stylus is moved into engagementwith the record and the reproducing stylus moved out of engagement with the same, the switch member 28 bein moved downwardly into electrical connectlon with theconductor 42, thereby closing the circuit from the battery 26 through the conductor transmitter 41, conductor 42',

switch'member28', conductor 27, receiver 20', and conductor 29 and back to the bat tery 26. At the same time the valve member rolls to the right, referring to Fig. 2, down the horn 43 and closes the opening 44 so as to shut the horn oil from the rest of the apparatus. Undulations correspond ing to the sound waves impressed upon the transmitter 41' T are now conveyed to the receiver 20', impressed upon. the diaphragm 7, and recorded in the surface 12 by the stylus 10. The operation of the member 14 to the right will again move the parts into the position shown in Fig. 2. y

The two forms of my invention shown in the drawing are merely illustrative of my invention and are not to beconsidered as limiting the latter in any manner, as many modifications may be made without departin p from the spirit of my invention.-
